This article comprehensively elaborates material characteristics, equipment advantages, complete production processes, detailed investment and operation cost analysis, capacity benefits, and scientific selection guidelines, providing practical and systematic technical and investment references for global thermoforming processing enterprises.
1. Thermoforming Grade Material Characteristics and Industrial Application Value
1.1 PP Sheet for General Thermoforming Scenarios
Polypropylene (PP) sheet is the most versatile thermoforming-grade plastic sheet, featuring low density, excellent chemical stability, high temperature resistance, and outstanding ductility. Thermoforming-grade PP sheets have uniform molecular structure, moderate melt strength, and excellent heating stretching performance, which can adapt to complex blister molding, folding, and deep-drawing thermoforming processes. The material is non-toxic, odorless, and compliant with daily product and food contact safety standards, making it suitable for disposable lunch boxes, fruit and vegetable packaging trays, cold fresh packaging shells, and ordinary industrial blister packaging.
In actual production and application, PP sheets have prominent cost advantages compared with PET and PVC sheets, with lower raw material prices and simpler molding processes. However, pure PP materials have sensitive temperature characteristics and are prone to uneven plasticization and sheet warping if the extrusion temperature and speed are not precisely controlled. Professional targeted extrusion equipment is required to stabilize sheet flatness and thermoforming consistency for long-term mass production.
1.2 HIPS Sheet for High-Rigidity Thermoforming Products
High Impact Polystyrene (HIPS) sheet is a specialized thermoforming material with high rigidity, high impact resistance, and excellent surface hardness. Different from flexible PP sheets, HIPS sheets have stable dimensional rigidity after thermoforming, not easy to deform or bend, and have good printing and surface finishing performance. The material has low shrinkage rate after molding, high product dimensional accuracy, and is widely used in high-precision electronic product packaging trays, hardware tool packaging, cosmetic outer packaging, and household appliance inner lining components.
Thermoforming-grade HIPS sheets require strict control of internal stress and surface smoothness. Ordinary extrusion equipment tends to cause residual internal stress in HIPS sheets, resulting in post-molding warping, cracking, and size deviation. Professional optimized extrusion lines adopt graded plasticization and slow cooling setting processes to eliminate internal stress, ensuring stable thermoforming performance and long-term dimensional stability of finished HIPS products.
1.3 PP+CaCO3 Composite Sheet for Ultra-Low-Cost Mass Production
PP+CaCO3 composite sheet is a modified environmentally friendly material formed by blending PP resin with calcium carbonate filler in a certain proportion. Calcium carbonate is a low-cost, high-hardness, and high-thermal-conductivity inorganic filler, which can effectively replace part of PP raw materials and significantly reduce raw material costs. The composite material improves the thermal conductivity of the sheet, accelerates extrusion cooling molding speed, and enhances sheet rigidity, wear resistance, and compression resistance compared with pure PP sheets.
The most prominent advantage of PP+CaCO3 sheets is ultra-low comprehensive production cost. Under the premise of meeting thermoforming basic performance, the calcium carbonate filling ratio can be flexibly adjusted from 15% to 40%, greatly reducing the consumption of expensive PP resin. In addition, the modified sheet has stable molding performance, low shrinkage rate, and good thermoforming reproducibility, which is very suitable for large-batch, low-profit, standardized thermoforming product production such as disposable tableware, industrial packaging gaskets, and logistics turnover trays.
However, improper extrusion processes will lead to uneven dispersion of calcium carbonate particles, sheet surface roughness, brittle texture, and reduced thermoforming ductility. Cost-optimized professional extrusion equipment must have efficient mixing and dispersion functions to ensure uniform filler distribution and stable comprehensive performance of composite sheets.
2. Common Defects of Traditional Extrusion Equipment in Thermoforming Sheet Production
2.1 Poor Material Adaptability and Unstable Plasticization
Most universal sheet extrusion equipment on the market is designed for single pure plastic materials, lacking targeted process optimization for HIPS high-rigidity plasticization and PP+CaCO3 filler mixing and dispersion. Traditional single-screw equipment has simple shearing and mixing functions, unable to fully disperse calcium carbonate fillers, resulting in particle agglomeration, sheet surface particles, and uneven thickness. For HIPS materials, ordinary equipment has excessive shear force, causing material molecular chain breakage, reduced impact resistance, and unstable thermoforming performance of finished sheets.
2.2 High Unit Energy Consumption and Low Production Efficiency
Traditional extrusion lines adopt fixed heating power and non-frequency conversion motor drive, with low heating efficiency and serious heat loss. Long-term idle and low-load operation causes massive energy waste. Especially in PP+CaCO3 composite production, uneven plasticization leads to low single-machine output, requiring repeated processing and resulting in increased power consumption per kilogram of finished products. The unoptimized cooling system has slow molding speed, restricting line speed and overall production capacity, unable to meet large-batch cost-controlled production needs.
2.3 Low Material Utilization Rate and High Comprehensive Cost
Ordinary extrusion equipment has low precision in feeding, plasticization, and calendering links, resulting in large sheet thickness tolerance, poor flatness, and high defective rate. The defective rate of traditional lines for PP+CaCO3 composite sheets is as high as 7%-10%, and the edge trimming waste is large, with a comprehensive material utilization rate of only 88%-92%. A large amount of raw material waste offsets the raw material cost advantage of calcium carbonate modification, leading to no obvious profit improvement in actual production.
2.4 Unstable Thermoforming Adaptability of Finished Sheets
Sheets produced by traditional equipment have large residual internal stress, uneven internal texture, and inconsistent heating ductility. During secondary thermoforming processing, problems such as uneven stretching, local thinning, product warping, and cracking are prone to occur, resulting in low yield of thermoformed products. The poor batch consistency of sheets makes it impossible for downstream enterprises to achieve standardized automatic production, increasing downstream processing costs and product scrap rate.
3. Core Cost-Optimized Advantages of Yuansu PP/HIPS/PP+CaCO3 Sheet Extrusion Line
3.1 Multi-Material Adaptive Screw Plasticization System
Yuansu independently develops customized screw and barrel structures for PP, HIPS, and PP+CaCO3 three types of thermoforming materials, solving the plasticization and dispersion pain points of traditional equipment.

4. Complete Production Process of Thermoforming-Grade Sheet Extrusion Line
4.1 Raw Material Proportioning and Mixing
According to production requirements of PP pure sheet, HIPS sheet, and PP+CaCO3 composite sheet, the intelligent automatic batching system accurately weighs PP particles, HIPS particles, calcium carbonate filler, and auxiliary agents such as dispersants and tougheners. For composite materials, the high-speed mixing equipment fully stirs and blends the filler and resin matrix to ensure preliminary uniform mixing, avoiding filler precipitation and agglomeration in subsequent extrusion processes. The closed mixing environment prevents dust and impurity pollution, ensuring high purity and stable formula of raw materials.
4.2 Automatic Feeding and Drying Treatment
The uniformly mixed raw materials are conveyed to the extruder feeding bin through a fully automatic vacuum feeding machine, realizing dust-free and pollution-free feeding.

The matched low-temperature dehumidifying and drying equipment strictly controls raw material moisture below 0.02%, ensuring smooth surface and stable internal structure of finished sheets.
4.3 Precision Screw Plasticization and Extrusion
Raw materials enter the screw barrel system for graded heating, shearing, and plasticization. Through multi-stage temperature zoning control, the materials are completely melted into uniform and stable melt. The professional screw structure ensures sufficient dispersion and mixing of calcium carbonate fillers in PP+CaCO3 production, and stable molecular structure of HIPS and PP pure materials. The melt is extruded stably under constant pressure, avoiding material degradation and performance attenuation caused by excessive shear and overheating.
